摘要

本文介绍了非线性动力学和混沌的实现及其在安全消息通信中的应用的最新进展。采用基于非线性电阻的混沌振荡器作为发射端和接收端的混沌发生器。对混沌扩频保密通信现象进行了实验研究。由混沌发生器产生的混沌信号与要传输的消息信号进行调制，随后使用在接收端产生的相同混沌信号进行解调，以实现安全的消息通信。本文给出了实验研究的结果。

On the realization and design of chaotic spread spectrum modulation technique for secure data transmission

In this paper, an exciting recent development in non-linear dynamics and realization of Chaos and its applications in Secure Message Communication is presented. The Chaos oscillator based on non-linear resistor has been taken as Chaos generator at the transmitting and receiving side. The phenomenon of secure communication with chaos spread spectrum has been investigated experimentally. A Chaos signal which has been generated from a chaos generator has been modulated with the message signal to be transmitted, and subsequently demodulated using the same chaotic signal generated at the receiving end, to enable secure message communication. The results of experimental investigation have been presented in the paper.
